In 2025, the Trump administration handpicked five climate science deniers to form the Climate Working Group and tasked it with working in secret on a biased report to justify the administration’s efforts to stop regulating the pollution that causes climate change.

That report targeted the U.S. Environmental Protection Agency’s bedrock determination that climate pollution harms human health and welfare, known as the Endangerment Finding. That 2009 Finding was based on a robust scientific record (PDF), which has only become stronger since then.

EDF and the Union of Concerned Scientists filed suit against the Trump administration under the Federal Advisory Committee Act, and a federal judge ruled that the administration violated the law by convening the Climate Working Group without open meetings, public records or balanced representation of viewpoints.

The judge also ordered the Trump administration to turn over the records of the Climate Working Group. In response, the government released multiple batches of records to EDF and the Union of Concerned Scientists.

On January 22, 2026, EDF and UCS released an initial key set of records, and EDF filed a supplemental comment (PDF) to the EPA detailing how Department of Energy political appointees facilitated coordination — in secret — between the Climate Working Group members and the EPA, with the specific goal of targeting the EPA’s Endangerment Finding.

EDF and UCS are now making the entire set of more than 100,153 pages of government records we received available to the public. These records show the Trump administration’s disregard for public health and contempt for rigorous science in their reckless, hasty effort to distort scientific facts on climate change.
